Description of key information
Parent compound: In contact with water the substance will hydrolyse rapidly (t1/2 < 24 h).
Hydrolysis products: hydroytically stable, but susceptible to biodegradation
Key value for chemical safety assessment
Additional information
Acid chlorides, coco
The substance is a mixture of the following components which hydrolyse rapidly in water to form HCl (CAS 7647-01-0) and the corresponding acid.
1) Lauroyl
chloride (CAS 112-16-3): >=30 to <=70%
(hydrolysis product: lauric acid, CAS 143-07-7)
2)
Tetradecanoyl choride (myristoyl chloride; CAS 112-64-1): >=10 to <=30%
(hydrolysis product: myristic acid, CAS 544-63-8)
3)
Palmitoyl chloride (CAS 112-67-4): >=1 to <=20%
(hydrolysis product: palmitic acid, CAS 57-10-3)
4) Decanoyl chloride (CAS 112-13-0): >=1 to <=15%
(hydrolysis product: decanoic acid, CAS 334-48-5)
5) Stearoyl chloride (CAS 112-76-5): >=1 to <=15%
(hydrolysis product: stearic acid, CAS 57-11-4)
6) Octanoyl chloride (CAS 111-64-8): <=1 to <=10%
(hydrolysis product: octanoic acid, CAS 124-07-2)
No experimental data are available on the hydrolysis of acid chlorides, coco (CAS 68187 -89 -3). However, experimental data are available for structurally similar substances.
Parent compound: Based on a weight-of-evidence approach, acid chlorides, coco are determined to hydrolyse rapidly to the corresponding acids and HCl. This is confirmed by read across to the analogue substances stearoyl chloride (CAS 112 -76 -5), 2-ethylhexanoyl chloride (CAS 760 -67 -8), pivaloyl chloride (CAS 3282 -30 -2), neodecanoyl chloride (CAS 40292 -82 -8) and nonanyl chloride (CAS 764-85 -2). All these compounds hydrolyse rapidly (<< 24 h) to the corresponding acid and HCl.
The measured data are supported by HYDROWIN 2.00 data which indicate that acyl halides usually have hydrolytic half-lives of less than 10 minutes.
Hydrolysis products: The acid chlorides hydrolyse rapidly to form the corresponding acid and HCl, which is inorganic. Based on expert judgement, the acids are hydrolytically stable, but suscpetible to biodegradation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
